How to square file

[Federico]

[QUOTE = "kfd518, post: 942875, membro: 6132"] Perdona il vecchio file funky che era già nel camion. Uso un angolo della piastra superiore poco profondo e un angolo della piastra laterale sufficiente per ottenere un taglio del foro decente e autoalimentazione.
La catena è allentata in queste immagini ma sta solo cercando di dare un'idea degli angoli dei file.

Filed a little more tonight, I think I need more down angle but I feel like I'm getting more consistent. It cut like a champ but needs more self feed. Which part of the cutter affects feed?

Looks like the rakers need to be taken down some even with perfect angles the chains still won’t self feed.

I'll take a few swipes off the rakers and give her another try.

Compare your toof to this and look at the angles. Little bit of forward lean on the side plate will help self feed. Don't go nuts on the raker, you're not far back on the tooth yet.

So just a few degrees back instead of strait up and down on the side plate?

I think he meant a few degrees of forward lean. Anything that makes the tooth more pokey will help it self feed

 

[Xr650jkallen]

Gotcha, I'll make her more pokey

Yep, I did.

This is my first experience with a square cutter, so I'm not real sure how much different it should feel while in the cut.

For me it felt smoother and faster, I was a square virgin also

It all depends on the angles. Really sharp with forward lean will be really aggressive with .025 rakers. On the other hand, blunt angles with minimal forward lean and .030" rakers can be smooth even on a 50cc saw.

346 runs this just fine. .028" rakers

 

[Xr650jkallen]

Geez yeah my rakers are definitely a little conservative. It was very smooth cutting and fast, I just had to pull up on the saw to get it to go.

Go by your saw chips. What do they look like? Square filed chain generally speaking makes a larger chip than round filed does.

 

[Skeans1]

All these chains have different power heads they live on so the grind is adjusted depending on one it’s used on. One is a 60” the full skip that goes on a 395, one is a 42” semi skip that can go on a 395 or a 390 which the tooth won’t be enlarged like it will be for the 395, the 36” can live on the 372, 390, or the 395 in which case the 372 grind will difference like the 42 but the 390 or 395 will share the same grind with a sprocket change, and the last is a 32” which can live on all the above as well as a 562.

It should cut like budda

 

[mettee]

I'll do some angle pics for you here in a bit that show file angles that should be used during every stroke. It's hard to describe
